Automated cross browser testing built in

Modern web applications must work across a huge range of browsers, devices, and screen sizes.

Chrome. Edge. Firefox. Tablets. Ultra-wide monitors. Mobile devices on slow networks.

Each combination creates variation, and variation is where bugs hide.

DoesQA makes cross browser testing part of your normal workflow so you can expand coverage without multiplying complexity.

Why cross browser testing matters

Browsers, devices, and viewports create a near infinite number of variations.

Even small differences in rendering engines, layout handling, or network behaviour can introduce subtle regressions.

Automated cross browser tests help you:

• Catch layout breaks before customers do

• Prevent browser specific regressions

• Validate responsive designs across viewports

• Ensure features work on real world configurations

• Ship with greater confidence across environments

Cross browser coverage is not just about compatibility. It is about reliability at scale.

Real browsers on real machines

DoesQA runs tests on bespoke test runners powered by real machines with real browser installations.

You can run tests across:

• Chrome

• Firefox

• Edge

Choose from 15 browser variants, including:

• Portrait Edge Tablet

• Chrome ultra wide

• Firefox desktop

• And more

This is not emulation inside a headless abstraction. These are real browser environments managed and maintained for you.

Simulated devices with real constraints

Increase your confidence even further with simulated devices.

DoesQA supports over 40 mobile, tablet, and smart display profiles that go beyond simple viewport resizing.

Simulated devices include:

• Accurate viewport dimensions

• Network speed simulation

• Device capabilities

• Pixel density

This allows you to validate how your application behaves under realistic conditions without maintaining separate device labs.

Expand coverage without expanding maintenance

Because cross browser testing is built directly into DoesQA, you can:

• Run the same flow across multiple browsers

• Use branching to handle browser specific variations

• Preserve concurrency for parallel runs

• Avoid duplicating test logic

You get broader coverage without duplicating work or increasing operational overhead.

Cross browser testing becomes a multiplier, not a maintenance burden.
